"Protestants are very suspicious of the Catholic view because it makes the believer look inside himself for his trust in his justification. “God is pleased with me because of something in me — grace in me, or works I have done, etc.” The Reformers insist that believers look to what Christ has done, and to that alone. Not that justifying faith is ever alone, but that faith is the way we receive what Christ has a done".
This was a comment on Monsignor's page. My question is that which we look inside ourselves for, in my understanding is the that which comes directly from the Holy Trinity which is granted and strengthened by the Sacraments that were instituted by Christ to give grace.
